driver: media: tegra: Update the power state.
bug 1457201
Update the power state when powe on. Or it will cause power off failure.
For instance, when the first time invoking ov5693_pm_wr to set the pwr_dev to 2,
the second time to power off ov5693 will be failure if the ov5693 is already on
but not updating the power state.
